Method Token

opensca/sca/java/xml/xml.go:271–331

Token returns the next XML token in the input stream. At the end of the input stream, Token returns nil, io.EOF. Slices of bytes in the returned token data refer to the parser's internal buffer and remain valid only until the next call to Token. To acquire a copy of the bytes, call CopyToken or the
